Abstract

Abstract New series of ω-(3, 8-diamino-6-phenanthridinyl) alkanoic acids are obtained from the acid chloride-esters ROCO (CH 2) n COCl (n= 0, 3 to 8; R= Me or Et). Reaction of these with 2-amino-3, 8-dicarbethoxyaminobiphenyl leads to the expected 2-acylamino-3, 8- dicarbethoxy-aminobiphenyls which by cyclization lead to the corresponding methyl or ethyl (3, 8-dicarbe-thoxyamino-6-phenanthridinyl) alkanoates. Quaternarization followed by ...
